Office 365 SMTP Server Problem with emailalert@emc.com

Hi,

We have upgraded the FLARE OE for VNX5100 lately.  We are using Distributed Monitoring (Instead of ESRS).

However, there is problem when Email is delivered to ‘emailalert@emc.com’.  According to EMC, it is a problem of MS Exchange Server (Office 365).

Just wonder is there any fellow encounter the same problem.  Is there any workaround for this problem ?

Thanks
